Commit 9b99d2a ("[build] Avoid generating ROMs with "match-any" vendor
or device IDs") introduced a regression which caused the UNDI PCI
driver to be omitted from the list of all drivers, and thus to be
excluded from the all-drivers build.
Fix by ensuring that the per-driver section of the Makefile is
generated even when there are no ROMs to be built.

WinPE has been observed to call PXENV_UNDI_SHUTDOWN but not
PXENV_STOP_UNDI. This means that Hermon hardware is left partially
active (firmware running and one event queue mapped) when WinPE starts
up, which can cause a Blue Screen of Death.
Fix by ensuring that the hardware is left quiescent (with the firmware
stopped) when no interfaces are open.

Specify a driver name of "undionly" and a device name based on the
UNDI-reported underlying hardware device. For example:
net0: 52:54:00:12:34:56 using undionly on UNDI-PCI00:03.0 (open)

Drivers are currently expected to initialise only the hardware
address, with the link-layer protocol code taking care of converting
this into a valid link-layer address. Some drivers (e.g. undinet) can
legitimately determine both the hardware and link-layer addresses,
which may differ.
Allow for this situation by checking to see if the link-layer address
is empty before initialising it from the hardware address.

Some BIOSes are reported to corrupt %ebx when using INT 15,2401 (see

The "sleep" command is generally useful to have. For example:
:dhcp_retry
dhcp && goto dhcp_done
sleep 5
goto dhcp_retry
:dhcp_done
Make the "sleep" command available by default, leaving TIME_CMD
controlling only the (fairly specialist) "time" command.

Arbel seems to crash the system as soon as the first send WQE
completes on an RC queue pair. (NOPs complete successfully, so this
is a problem specific to the work queue rather than the completion
queue.) The cause of this problem has remained unknown for over a
year.
Check in the non-functioning code to avoid bit-rot, and in the hope
that someone will find the fix.

TCP currently neglects to allow sufficient space for its own headers
when allocating I/O buffers. This problem is masked by the fact that
the maximum link-layer header size (802.11) is substantially larger
than the common Ethernet link-layer header.
Fix by allowing sufficient space for any TCP headers, as well as the
network-layer and link-layer headers.

CRLF line terminators are allowed in scripts; the carriage return is
simply interpreted as trailing whitespace and so is ignored. This
fails on lines containing script labels, since the label-finding code
checks for a line containing only the ":" marker and the label itself
(without any trailing whitespace).
Fix by allowing a label to be terminated by either a NUL or a
whitespace character.

According to section 14.23 of RFC2616, an HTTP Host header without
port implies the default port is used. Thus, when fetching from
anywhere but port 80 for HTTP or 443 for HTTPS, the port ought to be
explicitly given in that header. Otherwise, some servers might fail
to associate the request with the correct virtual host or generate
incorrect self-referencing URLs.
